I believe they mean it can't effectively be sold if everyone has it. It loses value as a commodity if anyone can access it, but the value of the data is still in tact.
But facebook is not in the business of selling your data. It's in the business of selling your attention and it uses data to do so. There's nothing about this leak that changes Facebook's position in this market in this regard.
